Sticky Dwell Click is a different type of click interaction task for Windows Control. Once you have selected the Sticky Dwell Click task the mouse cursor starts following your gaze, emulating mouse movement. When you fixate your gaze anywhere on the desktop or in applications it will activate a Dwell timer that will end in a click. By activating it with secondary selection you set it to activate a zoom before the click, meant for smaller targets.
Being “sticky” means that once you select this task, you don’t have to go back and reselect it again after it clicks. You can deactivate it by looking back at the icon on the Taskbar again or choosing any other task.
